12-Hydroxy-9(10®20)-5aH-abeo-abieta-1(10),8(9),12(13)-triene-11,14-dione (quinone 2) served as the dienophile in numerous intermolecular Diels-Alder reactions. These cycloadditions were conducted either thermally (including microwave heating) or wit

A new manganese(I) N-heterocyclic carbene electrocatalyst containing a benzimidazole–pyrimidine-based ligand is reported for the two-electron conversion of CO2. The increased π acidity of pyrimidine shifts the two-electron reduction to −1.77 V v

The CO2-reduction activity of two Re(I)–NHC complexes is investigated employing a silicon nanowire photoelectrode to drive catalysis. Photovoltages greater than 440 mV are observed along with excellent selectivity towards CO over H2 formation. The

New insights into [18]annulene were gained by looking more closely at its X-ray structure, revealing a close face-to-face stacking of 3.16 A in a herringbone-like crystal packing. Hexadehydro[18]annulene was co-crystalized in a benzene matrix, demons

A biomimetic synthesis of the triterpene (±)-perovskone was achieved featuring a remarkable polycyclization process in which three rings, four bonds, and five stereocenters were created in a single operation in 82% yield. This convergent synthesis r
